May need Covid-19 vaccine booster shots for emerging variants: AIIMS Chief
With various mutations of the SARS-CoV-2 emerging in the near future, there might be a need for the country to adopt a booster dose with second-generation Covid-19 vaccines, said All India Institute of Medical Sciences (AIIMS) chief Dr Randeep Guleria."It seems that we probably need the booster dose of vaccines as with the passage of time the immunity tends to fall. There is waning immunity. We would like to have booster dose that will cover for various emerging variants," Dr Guleria said in an interview with ANI.
